Before
- Tubing selection relied on a spreadsheet calculator.
- Growers needed help to match tubing to their flow rates, implement width and speed.
After
- Growers enter implement width, tynes, speed range, target rate and liquid type.
- The app works out flow per tyne and matches the right tubing automatically.
- Guests see basic results. Registered growers get the full breakdown.
